You can't find the code because it doesn't exist!  Gorm sets up the 
interface using ObjC calls then writes out the objects themselves in a 
binary archive format.  But of course it is possible to do such setup 
"manually" in Objective-C.  Others will be able to advise you here 
better than I, but for example there are various methods in NSView and 
NSMatrix relating to this.  I'm pretty sure there are tutorials out 
there, either from Apple or otherwise.

Also, for GNUstep there is a middle ground approach between Gorm and 
manual ObjC in which you write XML describing the interface -- see 
http://www.gnustep.it/Renaissance/

Most current apps use a combination of Gorm with some manual 
specification.
